A Labour frontbencher has been suspended after the party received a complaint about his behaviour, Sky News understands.

Shadow foreign minister Bambos Charalambous has been “administratively suspended” from the party pending an investigation – meaning he has lost the whip and will sit in the Commons as an independent MP.

Mr Charalambous, the MP for Enfield Southgate, said he was “aware that there is an allegation that requires investigation by the Labour Party”.

“It is right and proper that process is allowed to take place,” he tweeted. “I will cooperate fully and play my full part.

“It is not appropriate to say anything further at this time.”

The Guardian, which first reported the suspension, said the complaint had been submitted to Labour’s independent complaints process.

Since the 2019 general election, nine Labour MPs have lost the whip and not had it restored.
